EV RANGE OF THE CAMERA—continued

How to read the EV chart

Full-aperture metering

Example: Lens maximum aperture: f/1.4

ASA film speed: 100

Working aperture: f/5.6

By referring to the f/1.4 column in Section A and the

EV values Indicated for ASA 100 In Section D, you will

find that the EV range for an f/1.4 lens at ASA 100 is

1 to 18. Now, refer to Section В and single out the

f/5.6 Indication for ASA 100. Go diagonally down

until the protruding line intersects with Section C’s

vertical line for the shutter speed of 8 sec. (the EE’s

slowest shutter speed). From this point of intersection,

follow the horizontal line that leads to Section D*s

EV value for ASA 100, and you will obtain an EV

value of 2. Start again from the f/5.6 indication for

ASA 100 in Section B, and go down diagonally until

the protruding line intersects with Section C’s verti

cal line for the shutter speed of 1/1000 sec. (the EE’s

fastest shutter speed) this time. Then follow the hori

zontal line that leads to Section D’s EV value for ASA

100, and you will get a reading of EV 15. This means

that an f-stop of f/5.6 at ASA 100 and a shutter speed

of from 8 to 1/1000 sec. has an effective EV range of 2

to 15, which is well within the EE’s metering range of

EV 1 to EV 18. The area encompassed by the heavy

lines in Section C demonstrates a metering range for full

aperture method using an f/1.4 lens and ASA 100 film.

Stop-down metering

Example: ASA film speed: 100

Stopped-down aperture: f/8

The procedure is the same. The f/8 column in Section A

and the EV values indicated for ASA 100 in Section D

will show you that the EV range for f/8 is 6 to 23. Refer

now to Section В and single out f/8 at ASA 100. Go

diagonally down until the protruding line intersects with

Section C’s vertical line for the shutter speed of 8 sec.

From this point of intersection, follow the horizontal

ine that leads to Section D’s EV value for ASA 100, and

you will obtain an EV reading of 3. This means that an

f/stop of f/8 at ASA 100 and a shutter speed of 8 sec.

give an EV value outside the metering range. To find

out the slowest shutter speed usable, follow the f/8 indi

cation for ASA 100 in Section В diagonally down until

it intersects the horizontal line in Section C that leads

to Section D's EV value of 6 for ASA 100, and you will

find that the slowest shutter speed usable is 1 sec. In

other words, at f/8 and ASA 100, the available shutter

speed range that is within the metering range is from 1

to 1/1000 sec., which has an effective EV range of 6 to

16 (indicated by the broken line In Section C)—well

within the metering range.

In practice, you will find that it is generally the high

end and the low end which require a careful check.

The EV range of the Nikon EE encompasses most

ighting situations, and it is only under dim-light or

extra-bright picture-taking situations that you need pay

any special attention.
